Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic wire rod setting device such as a header that automatically sets a wire rod of material in a processing device such as a header.

Conventionally, the material supplied to the header is a long wire wound into a coil.
Since it is difficult to connect the end of one coiled wire to the tip of the next coiled wire,
Normally, when one coiled wire is set in the carrier and used up to the terminal, the worker stops the header, sets the next coiled wire in the carrier, and attaches the tip of the wire to the header. The header is then set on the feed roller that has been installed, and then the header operation is restarted.

However, it is usually not possible to manufacture extremely long and large coiled wire rods due to manufacturing and transportation constraints, and for this reason, in the case of high-speed headers, one coiled wire rod can be used to connect two or more headers. It can only be operated for 3 hours, and therefore, workers have to perform the above-mentioned work many times a day, which is troublesome. The task of setting the header to the header is particularly difficult.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to extract the end of the wire left in a processing device such as a header with a relatively simple configuration, and to

Next, the operation of the above configuration will be explained. In the original position shown in FIGS. 1 and 4, the base 1 is located to the right of the header 2, and the rotary carrier 22, which is located to the left in FIG. It is located at the corresponding wire rod feeding position. Then, the wire guide 6 with the wire rod 79 wound in a coil shape placed on the rotating carrier 22 located at the wire rod feeding position together with the wire rod carrier 78 is closed.
8, 68 and the straightening roller 4 of the wire straightening machine 37
The wire rod is supplied to the header 2 from the wire guide pipe 77 via the wire rods 0, 40 and 41, 41 in order, and the wire rod 7
The wire rod 79 is intermittently fed into the header 2 by a feed roller, and the wire rod 79 is sequentially cut around the periphery and forged in multiple stages to continuously produce a forged product. In this state, in the setting device 35, as shown in FIG. 4, the movable frame 59 is in the neutral position, the movable arm 62 is located in a position close to the clamp head 65, the fingers 63, 63, the guide finger 66, 66 is in an open state, the straightening rollers 40, 40 and 41, 41 of the wire straightening machine 37 are closed and sandwiching the wire 79, and the feed rollers 45, 45 of the wire rod feeding device 42 are in an open state. There is. Further, the carrier loader 3 is positioned with a stopper pin 16 engaged with one of the stoppers 15, and its rotation is regulated by the braking force of the brake motor 11 with a reduction gear.

In this state, the rotating carrier 22 located on the right side is unrelated to the operation of the header, and therefore the header 2 is operated by the wire rod 79 set in the rotating carrier 22 on the left side. In the meantime, a new coiled wire 79 is placed on the right rotating carrier 22 together with the wire carrier 78. This mounting work may be carried out manually by an operator using a crane or the like, or may be carried out by a robot or the like for the mounting work. And wire rod 7
9 and the rotating carrier 22 together with the wire carrier 78.
Once set upward, the air cylinder 28 is extended, the air cylinder 32 is contracted, and the tip of the wire 79 is connected between the fixed claw 31 and the movable claw 33 of the wire clamp 30.
After insertion, the air cylinder 32 is extended to connect the fixed claw 31 and the movable claw 3 of the wire clamp 30.
The tip of the wire 79 is clamped between the wire 79 and the wire 79 (see FIG. 3).

Next, when the wire rod 79 placed on the left rotary carrier 22 is used to the end, this is detected by the end detection device 70 and a material feed stop signal is given to the header 2. Then, in the header 2, the link transmitting the rotation of the crankshaft to the feed roller is separated from the crank by a solenoid valve or the like, and the operation of the feed roller, that is, the wire feeding operation is stopped. After the wire feeding operation is stopped, the header 2 continues to operate by a timer until the final cut piece becomes a product, and then the header 2 is braked in an emergency manner, and the clamp shaft of the header 2 is rotated in accordance with the patent application filed by the present applicant in 1983. As disclosed in No. 136479, it is stopped at a rotational position suitable for restarting operation.

When the wire feeding operation is stopped, the air cylinders 64 and 67 are contracted and the fingers 63 and
63 and the guide fingers 66, 66 are closed, and the ends of the wire rod 79 are in the clamp recesses 63a, 63a.
The correction rollers 40, 40 and 41, 41, which are sandwiched therebetween and are slidably held in the guide recesses 66a, 66a and are closed at the same time, are opened by the contraction of the air cylinder 46. Next, gear motor 5
5 rotates the drive shaft 54 in one direction, and the feed screw 54a moves the moving arm 62 in the direction of the rotary carrier 22, that is, in the direction of arrow A. Then,
The wire rod 79 slides against the guide recesses 66a, 66a of the guide fingers 66, 66, and clamps the clamp recesses 63a, 63 of the fingers 63, 63.
When the movable arm 62 is pulled out in the direction of arrow A and moved to the maximum in the direction of arrow A,
The air cylinders 64, 67 are extended to open the fingers 63, 63 and the guide fingers 66, 66, and the air cylinder 60 is contracted to move the movable frame 59 at a predetermined angle in the direction of arrow B from the position shown in FIG. At the same time, the air cylinder 75
is contracted, and the discharge bar 74 of the residual material discharge device 73 is rotated in the direction of arrow C, so that the fingers 63,
63 and the end of the wire 79 pulled out from the header 2 by the guide fingers 66, 66 is connected to the base 3.
6 It is dumped on the floor in front of you. On the other hand, as soon as the operation of the header 2 is stopped, the brake motor 11 with a reducer is rotated in the forward direction to move the carrier loader 3 to the direction indicated by the arrow D.
Rotate 180 degrees in the direction of the rotation carrier 22 on the right side.
is moved to the wire rod feeding position on the left side, and at the same time, the empty wire rod carrier 22 on the left side is moved to the right side. In this case, when the carrier loader 3 rotates 180 degrees, one of the limit switches 34 is activated to cut off the power to the brake motor 11 with a reduction gear and perform braking, and the stopper pin 16 engages with the other stopper 15. The positioning is done. Then, as described above, when the end of the wire rod 79 is discarded and the rotation of the carrier loader 3 is completed,
The air cylinder 60 is extended and the movable frame 59
is further rotated in the opposite direction of arrow B than the neutral position shown in FIG. 64 is contracted and the wire rod 7 is placed in the clamp recesses 66a, 66a.
After the clamping, the air cylinder 32 is contracted to release the clamping by the wire clamp 30, the cylinder 28 is contracted, and the rotating arm 29 is rotated downward. After that, the air cylinder 60 is contracted and the movable frame 59 is moved to the fourth position.
It is returned to the neutral position shown in the figure. Next, motor 55
is rotated in the opposite direction to that described above, thereby the drive shaft 54 is rotated in the other direction, and the moving arm 62 is moved by the feed screw 54a in the direction of the header 2, that is, in the opposite direction of arrow A. Then, finger 63,
63, with the tip of the wire 79 clamped, moves in order between the wire guides 68, 68 in the released state, between the correction rollers 40, 40 and 41, 41, and between the feed rollers 45, 45, and then transfers it to the clamp. It stops at a position close to 65. Then, when the fingers 63, 63 pass between the wire guides 68, 68, the air cylinders 69, 69 are expanded, and the recesses 68 at the ends of the wire guides 68, 68 are expanded.
a, 68a, so that the moving arm 62 can now slideably guide the wire rod 79 inside the clamp head 6.
5, the air cylinder 67 is contracted and the tip of the wire rod 79 is slidably held in the guide recesses 66a, 66a of the guide fingers 66, 66, and at the same time, the air cylinder 49 is contracted. Then, the feed rollers 45, 45 are closed, and the wire rod 79 is sandwiched between the feed rollers 45, 45. Thereafter, the air cylinder 64 is extended to release the fingers 63, 63, and the motor 76 drives the feed rollers 45, 45 in the direction of the arrow E, so that the tip of the wire 79 reaches the guide fingers 66, 63.
is moved in the direction of arrow F while being guided by header 2.
The wire rod is fed into the wire guide pipe 77. and,
When the tip of the wire rod 79 is fed until it comes into contact with the wire rod stopper of the header 2, the setting operation of the wire rod 79 is completed, the air cylinders 67, 49 are extended, and the guide fingers 66, 66 and the feed rollers 45, 4 are extended.
5 is released, the air cylinder 46 is extended, and the straightening rollers 40, 40 and 41, 41 are closed,
At the same time, the fluid roller in header 2 (not shown)
is closed. After this, the operation of the header 2 can be restarted, and by repeating the above operation when the wire rod 79 has been used to the end, the header 2 can be automatically operated continuously.

It should be noted that the wire straightening machine 37 and the wire feeding device 42 may be arranged in such a way that the positions of the wire straightening machine 37 and the wire feeding device 42 are switched.
The wire straightening machine 37 may close the straightening rollers 40, 40 and 41, 41 at the same time as the feed rollers 45, 45 to sandwich the wire 79 when the moving arm 67 is stopped at a position close to the clamp head 65.

In addition, when replacing the wire rod 79 with a wire rod 79 of a different diameter during setup change without using the wire rod 79 all the way to the end, the tip of the wire rod 79 is removed by performing the reverse operation described above for setting the wire rod 79 in the middle of use. It is also possible to hold the wire rod 79 in the wire rod clamp 30, and the wire rod 79 can be easily replaced during use.

Furthermore, in the above-described embodiment, the rotating carriers 2 are alternately positioned at the wire rod feeding position as the carrier loader 3 rotates. Or use a crane etc. to make a new wire 79
